My flight went off without any hitch or issue. I anticipate issues every time I fly, luckily, I was wrong on this trip.

It was much better than expected. Short flight and smaller plane so no entertainment or food.

It took around two hours to depart. Just sitting in the tamarack waiting. It impacted my traveling plans in a very dramatic way. When we returned, it took around two hours for us to be able to get our luggage. Ridiculous!!

I thought every thing was good with the acceptation of the long layover between Seattle and the Tampa trip.

While the flight and the legroom was good boarding took a long time. The different groups Boarding made no sense as those in the back of the flight boarded last causing delays as people try to find room for their luggage in the upper bins. While there were plenty of seats on the flights We were spaced so that some rows were filled and others were empty. My first flight was very crowded and uncomfortable. On the way back both flights did not have Wi-Fi nor the entertainment package. We were only made aware of this a few hours before the flight. Since the flight was in the morning, I was asleep and was not able to download Books or other media to my phone. This is my first time flying Alaska airlines and I will admit to thinking twice before I do so again.

Our flight was delayed by six hours, our plane never left Portland the night before but the airline didn’t inform anyone till two hours before a six am flight. The plane, our plane never left the west coast! No plane no flight, simply let folks know when you know, not hours and hours later. No one apologized, no one said much of anything, we were just expected to wait quietly and await instructions.

The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

Both flights were delayed. We sat on the tarmac on Boise for 3 hours with little updates

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

4 out of 4 flights cancelled or delayed. 5th trip with similar experience

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

Business class was economy with a table in the middle seat. That is worse than economy. No food and no entertainment. Very poor representation.

I like the plane , but i was 50 mts before my fly and they didn’t let me document my luggage, so they told my that I have to leave my luggage or buy an others tickets , because they didn’t want me to give me credit for the tickets I have so that is abuse from the company , and on the line it was 5 families with the same situation equal lime mine , I think they doing business with the tickets w people ,; Mexico has a bad working people, the rip money from turists, and is bad because give bad impression of the company that is aereomexico

No everybody brings the proper equipment to enjoy the plane entertainment. Then I was not able to enjoy it.

Pros: "I like the service ,the food in thos fliggt back. Excelent"
Cons: "Better rules for people who put the seat back while we eating ,some crewmembee could say something"
Pros: "Crew friendlynesd"
Cons: "Paying a little more attention to the seating. Not everyone was socially distanced. Seat rows were unequally distributed: some were all full others were too empty."
Pros: "Seat was okay, but I thought we weren't doing center seats because of Covid risk. That plane was packed tight."
Cons: "They made me store my bag, because I had a guitar which has always been allowed as a carry on. Its a fragile instrument, and has always been allowed as a carry on."
Pros: "Nothing"
Cons: "Everything, I will never going to use this software anymore."
Pros: "Flight was late, lost my conection and gave me a flight for next day"

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

So so. Terrible aircraft choice for that leg of the flight.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Terrible. 2 hour delay. Sat on the tarmac. Missed my connecting flight. Had to ARGUE with Customer service to get a hotel and food. Terrible experience with my loyal carrier

Our seat tv didn’t work All the rest was perfect

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I liked the exit row seat. Hated the distance between gates in Houston.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.
